Since Nokia announced its switch to Windows Phone 7, people have been worried about the future of Qt. Well, it turns out Nokia is still going full steam ahead with Qt, since it has just announced the plans for Qt 5.

There will be no distinction between a Nokia developer or third party developer.

If most machines include dedicated hardware for graphics why not optimise for the majority?

Last but not least...since when have any accelerated uis needed Gaming level gpus?
